## Abstract Constitutive equations are derived for the nonlinear viscoelastic behavior of amorphous glassy polymers. The model is based on the theory of cooperative relaxation in a version of the trapping concept. Stressβstrain relations are applied to fit experimental data for polycarbonate in the
Recent data on comparative osmotic deswelling of poly(acrylic acid) gels and solutions shows that the difference between osmotic pressure of the gel and of the solution, P gel (c, f ) 0 P solution (c, f ), taken at equal polymer concentration ( c) and fraction of the ionized acrylic acid monomers (
